Want SIRI on your iPhone 4?

First off you must be on iOS 5 and Jailbroken. The first is a SIRI like assistant available from Cydia. It's called E.S.R.A.

Second is SIRI but I have never tried this so I don't know how well this will work. Use at your own risk. This one is also available from Cydia.

NOTE: If you are having trouble with finding anything in Cydia it because you may not have the correct sources (repo) added. Hit me up for more info. ikingtrust@trustmythoughts.com
